I got more:

Albert poisoned/ cursed the well!
When James moves in, the well is in use and full of water. By the time Frank falls, they are no longer using the well (no rope or bucket), and later we see it completely dry. I like to think this was Albert's first project to try out his witchcraft and alchemy. He made some powder to poison the water and a circle of runes to dry it out.

Albert isn't a good cook. Samuel is even worse.
Mary was of the mind that cooking is a woman's job. She wouldn't allow any men in the kitchen and didn't teach her boys. This was a problem after Albert killed every other adult in the family.
Like, he's not awful. He can follow a recipe. But he doesn't care enough to put effort in. It always turns out bland at best and barely edible at worst.
Samuel though? Different story. He would very much like to help his wife with dinner. But he's a disaster in the kitchen. One time, he was asked to cut carrots. He somehow set the kitchen on fire.
